Grado Labs is pleased to announce the introduction of our newest product, the "iGrado" street style headphone. Designed specifically for the portable electronics market, it was our goal to design a street style headphone that will sonically outperform anything currently available in the low-end portable market. This we have accomplished. The new "iGrado" is functionally stylish, lightweight and comfortable. By incorporating the same drivers used in our highly regarded SR60 headphones, we can proudly state that we are indeed "the high end choice in the low end market." The "iGrado" features a behind the neck headband that is comfortable and stylish. We have indeed kept the highly praised Grado "sound" at a price point that is within reach of all. Truly, Musical Reality For The iWorld!
"The iGrado reproduces important midrange frequencies that are free of any discoloration and compression, with high frequencies sounding very decent and delicate. As a result there is indeed a tonal balance and characteristic which can hardly be topped in the portable world."
— HOME Electronics Magazine/Switzerland
"This price is ridiculous for the quality of sound you get, and when you compare them to other brands in that range (believe me, I've tested just about everything out there)."

What does the i stand for in the new SR125i from Grado? Improved, that's what! Grado's ability to combine lightness with extreme rigidity and internal damping has been put to good use on the SR125i. Based on the same design as theSR80i, the SR125i also features an improved driver and cable design utilizing UHPLC (Ultra-high purity, long crystal) copper voice coil wire. With the new 8 conductor cable design you will notice improved control and stability of the upper and lower range of the frequency spectrum, with both better supporting Grado's world renowned midrange. The Diaphragms are put through a special 'de-stressing' process in order to enhance inner detail. The way the SR125i's new driver, cable and plastic housing move air and react to sound vibrations are now less affected by transient distortions. Bass, midrange and treble are all more open and you will enjoy the fine tonal spread and balance.
"We all agreed the Grado SR125 headphones are excellent, and that they would be a fine choice for anyone looking first to audio quality"
— Paul Bergman / Ultra High Fidelity Magazine (Canada)
"For me the Grado SR125i's produce some of the best sounding vocals I have ever heard. I felt like Leona was singing in my living room. I was also impressed how well these headphones worked for gaming. I fired up NHL 09 and every puck that clanged off the goal post and every check that a player gave sounded better than every before. I had used a pair of Sennheiser headphones in the past with this game, and it was like I was listening to a different game. Overall these headphones impressed me on every level."

What does the i stand for in the new SR225i from Grado? Improved, that's what! Features are the same as the SR125i, new driver, cable and housing designs, but this headphone has an increased rear air flow, utilizes Grado's larger ear cushion and has closer matched drivers. Air flow is increased by 50% which is achieved through an improved rear metal screen. The use of closer matched drivers and the larger cushions results in an enlarged soundstage, while the improved rear screen frees the headphone from colorations.
"Music flows through this headphone organically and believably, with irrepressible dynamics and bounce."
— HI-FI Choice
"At $200, the SR-225i's deliver the essence of the top-of-the-line PS-1000's. That makes them practically a gift to anyone who loves music."

"The retro design makes these headphones look like they'd be more at home reproducing Mozart than pumping out Jay-Z. But looks can be deceiving: The gold colored cans churn out unrivaled sonics no matter what's sent through them. They produce strong, accurate bass, warm and natural mids, and crisp clean highs with almost no tonal coloration. They're impressively lightweight..."
— Chuck Tannert / Penthouse magazine
"This headphone has something magic: a rare musicality that preserves the natural elegance of the music. The medium is refreshing, natural and sensual. The richness of the harmonics in the medium pulls you in. The instruments have a credible texture. The spectral balance is good. The timbres are rich and at time exceptional. The definition is flawless; the music keeps its nuances and richness of expression."

 Professional Series PS1000
Grado Headphones
$1,695.00
Headphones

Grado is proud to introduce the new flagship of their headphone line, the PS1000. This hybrid design has an inner sleeve of a selected species of hand-crafted mahogany made by using an intricate curing process. Its outer housing of metal machined from a special non-resonant, very hard metal alloy utilizes a special processing and casting method to increase the porosity of the alloy. This combination of wood and metal insures that the earphone chamber has no "ringing" which might obscure detail or add coloration. The way the wood and metal housing moves air and reacts to sound vibrations is now virtually unaffected by transient distortions. Grado has also designed a new cable for the PS1000. The new eight-conductor cable design, utilizing UHPLC (ultra-high purity, long crystal) copper, improves control and stability of the total range of the frequency spectrum. The PS1000 also utilizes a newly re-configured voice coil and diaphragm design, resulting in unsurpassed speed and accuracy response. The cushion design creates the correct balance between the driver and hybrid housing to give the resulting musicality desired. The cushion design also makes the PS1000 one of the most comfortable to wear headphones in the world. Grado has taken all their knowledge and years of experience in controlling resonances and eliminating distortions and this has culminated in the development of their finest headphone ever, the PS1000.
"I've been listening to Grado headphones for over 15 years, and I have to say that the PS1000 is the greatest headphone theyve ever made."
— Mark Rivera, long time member of the Billy Joel Band & Musical Director for Ringo Star
"...we think the PS1000 is the best-looking and best-sounding headphone we've tested from the company. That also makes it one of the best pair of headphones we've ever heard."

The characteristics of the RS2i remain the same as its distinguished big brother, with the new species of hand crafted mahogany, but with a smaller wooden air chamber. Although a miniature version of the RS1i, the RS2i still maintains an overall sound that is pure Grado, warm harmonic color, full bodied vocals, excellent dynamics and ultra smooth top end. These truly are audiophiles dream.

What does the i stand for in the new GS1000i from Grado? Improved, that's what! Featuring a new species of handcrafted Mahogany earpieces made using an intricate curing process; Grado has been able to optimize the tonal quality. The GS1000i uses new upgraded dynamic transducers and the new 8 conductor cable design. All this, new wood, driver and cable designs result in improved control and stability of the upper and lower range of the frequency spectrum with both better supporting the GS1000i's new world renowned midrange.
Grado's GS1000i cushion design actually creates a "room" for the ears to sit, creating a larger soundstage and greater spatial experience for the listener. It was most important to design the correct balance between the driver and our wooden driver housing to give us the resulting sound that we desired. This has been accomplished. By creating this "room" for the ears to sit, positioning of the cushions with regards to the ears (i.e., forward or back) is somewhat critical in finding the absolute sweet spot.
With this cushion design, we believe the GS1000i to be one of the most comfortable headphones on the market today.
The GS1000i retains a sound that is pure Grado, rich full-bodied vocals, excellent dynamics and an ultra smooth top end. The presentation is very detailed, the bass is deep and the music is very tight and non-fatiguing. All with a soundstage that is huge allowing for unbelievable separation and layering of the music which is simply stunning.
Listen and enjoy!
"Each and every instrument has body and the vocals come across without any doubt or question. When you hear the sound of a voice, you can actually hear and feel the sound as it would be coming from a real human flesh and blood. These qualities, along with the immediate proximity of the headphone, allow the music to actually get right under your skin."

Grado, one of the oldest family owned companies in the Audio Industry, has for over half a century been the leaders in design engineering for the high-end audio and recording industries.Grado is famous for their remarkable headphone and phono cartridge designs and hold over 48 patents. Company founder, Joseph Grado is credited as the inventor of the stereo moving coil phono cartridge. He is responsible for more innovations in phono cartridge design than any other person in our lifetime and was inducted into the Audio Hall of Fame in 1982.
All Grado headphones have a vented diaphragm design that incorporates a large air chamber. This design concept lowers the frequency resonance (distortion) of the diaphragm and extends bass response. The diaphragm is made of a low mass polymer, carefully formed to broaden resonant modes to reduce their amplitude. The diaphragm mass is determined with the compliance of the suspension in mind so that the desired low frequency resonance is achieved. The diaphragm's total mass is calculated to provide a full 20 KHZ bandwidth, while avoiding break-up at lower frequencies.
The Professional, Statement, Reference Series and along with the Prestige Series SR325is, SR225i and SR125i feature voice-coils that are wound from ultra-high purity, long crystal (UHPLC) oxygen free copper. The copper is slowly drawn through the die in extremely small increments and is annealed following each drawing operation. Ultra-high conductivity copper yields the clearest transmission and lowest coloration possible. The sound of UHPLC copper is smoother, cleaner and more dynamic. All use very high power neodymium magnets to provide maximum efficiency and better sound. Each headphone driver is made to Grado's high standards, then pair-matched for exact imaging. These headphones also utilize UHPLC copper in the connecting cable.
All metal work for the PS1000 and SR325is is machined from a special non-resonant, very hard alloy. Grado utilizes a special processing method to increase the material's porosity. This complex treatment insures that the earphone chamber has no "ringing" which might obscure detail or add coloration.
Grado's wooden Statement and Reference Series are hand-crafted at our labs from a new specially selected species of mahogany. An intricate procedure of curing is done between production steps to achieve optimal sonic quality. The overall sound remains pure Grado, warm harmonic color, full bodied vocals, excellent dynamics and an ultra smooth top end.
Technical refinements for Grado drivers include improved diaphragm and voice coil design for increased bass response and a larger perceived sound stage. A unique process to "de-stress" the diaphragm results in enhanced inner detail. An increased ability to control driver resonance virtually eliminates distortion. For all models, an improved headband spring will afford greater comfort for the majority of listeners.
AND THE SOUND?
Grado headphones can reproduce as natural a soundstage from stereo recordings and provide as much listening pleasure as a good pair of speakers do. Grado headphones are free of room effects and placement problems, and they minimize any interference from external noise. They also offer portability and the ability to listen without worrying about the neighbors. With Grado headphones, you will hear recordings with greater clarity and with deeper bass than others! Grado headphones are the antithesis of mass production, as each Grado headphone is hand-assembled and closely scrutinized to meet full performance specifications in the U.S.A.
